check out some of the crowdfunding sites you can make 10-12% on short term loans and spread it around over multiple investments to minimize  risks,patch of land, realty shares etc

I would like to maximize the return and minimize the selling time.

One thing to consider as well, your fees for borrowing against your 401k are minimal.

Minimal of course.

But usually, I also buy homes with minimal down as there are a lot of owners that just do not want the headache of managing a house and renters.

It's a great way to put down a minimal amount of cash up front, while keeping some savings for your next deal.

I'm sure experienced investors can pull this off but I like to keep things simple and minimize my risk.  

Now that my facility is 93% occupied and my delinquents are minimal it's a great business. 

The problem is paying taxes--the more you make the more you pay --its a fact unless you figure out away to minimize your taxes.  

I have owned and operated a construction company, a property management company, and a mortgage broker company as well.I want to improve my real estate business with the use of technologies to minimize cost and maximize efficiency thus increasing my free time.
